Parker’s pilot operated pressure reducing valves are capable of flows up to 150 lpm (40 gpm) and regulating pressures up to 350 bar (5000 psi) and are commonly used for setting the pressure of a sub-circuit within a hydraulic system.

How does a pilot-operated or dome-loaded pressure reducing regulator work? A pilot-operated regulator amplifies slight changes in outlet pressure to the main valve, offering larger flow capability and maintaining outlet pressure closer to the setpoint.

Rexroth pilot-operated pressure reducing valves feature high stability and low hysteresis. Deviating from ISO 4401, port T is called TA and port T1 is called TB in this data sheet. Version "MS" is shown. With the standard version, port M is omitted. Version "SO30" is shown. The standard version does not have ports X and Y.

Parker’s pilot operated acting reducing & relieving valves are used in applications where specific functions require reduced and regulated pressure. Capable of flows up to 150 lpm (40 gpm) and pressures up to 380 bar (5500 psi).

Highly sensitive pilot valve provides a constant outlet pressure, irrespective of erratic inlet pressure or system demand. Provides very close accuracy of pressure control. Choice of bronze or carbon steel constructions. Threaded or flanged models available.

Valves of type DRE(M) are pilot operated pressure reducing valves. They are used to reduce an operating pressure. These valves basically consist of a pilot control valve (1) with proportional solenoid (2), a main valve (3) with main spool insert (4), …

The PREDU® P is a self-acting pilot operated pressure reducing valve for use on steam and air, that will accurately control downstream pressure (P 2), regardless of the upstream pressure (P 1), or demand from the system.

Pressure valves of type DR are pilot-operated pressure reducing valves controlled from the secondary circuit. The pressure reducing valves basically consist of the main valve (1) with main spool insert (3) and pilot control valve (2) with adjustment type. In …

Parker in-line mounted pilot operated pressure reducing valves series R4R ensure a constant pressure in the secondary part of the hydraulic system. Series R4R*P2 enables a continuous adjustment by the proportional solenoid operated pilot stage.

The ADCA PRV57 pilot operated pressure reducing valves are designed for use with steam, compressed air, nitrogen and other gases compatible with the construction materials. The PRV57 can be installed in pressure reducing stations throughout all industries, and provide sensitive and accurate control even when
